T 0 all whom it may concern:

Be it known that 1, WILLIAM S. MGMATH, a citizen of the United States, and a resident of El Paso, in the county of El Paso and State of Texas, have invented a new and 1mproved Job-Press Standardizer, of which the following is a full, clear, and exact description.

My invention has for its object to provide a standardizer for job presses which may be secured to the bed of a press, thereby permitting the use on the press of a chase from a smaller size press.

in most cases where presses of two sizes are used in a job press ofiice, nearly all of the work may be done on the smal er presses, but a few of the larger presses are required for use on large work. Then the small presses are in use and one of the larger preses is free, the chase for one of the smaller presses may with my standardizer be mounted on one of the larger presses. In this way practically all of the work is standardized on the smaller chases, and it is never necessary to change a form from a small chase to another chase for use on the larger press.

Additional objects of the invention will appear in the following specification, in which the preferred form of the invention is described.

In the drawings similar reference characters denote similar parts in all the views, in which- Figure l is a perspective view of a press bed with my standardizer mounted thereon, parts being brok n away to illustrate the construction; Fig. 2 is a front view of my standardizer, with a part broken away to illustrate the manner in which the movable pin is mounteo; Fig. 3 is a plan view of Fig. 2; and Fig. is a transverse sectional view of Fig. 3.

By referring to the drawings, it will be seen that my standardizer. 5 has a fixed pin 6 at one end and a guideway 7 at its other end, a pin 8 being disposed in the guide way 7. This pin 8 is held yieldingly eX- tended by means of a spring 9. The pin 8 may be locked in its outer position by means of a thumb-piece 10 which projects'from the pin 8 into a bayonet slot 11, it being un derstood that when the thumb-piece 10 is pressed downwardly in the outer portion of the bayonet slot 11, the pin 8 will be pre Specification of Letters Patent.

vented from moving inwardly. The standardizer 5 has an inclined bottom 12 for engagement by fingers 13 which serve to support the bottom of the standardizer 5, the fixed pin 6 being disposed in an orifice 14: in a frame 16 at one side of a press-bed 17, it being possible to move inwardly the pin 8 by means of the thumb-piece 10, so that the pin 8 may then be disposed in an orifice 18 in the other side frame 19 of tie pressbed. The fingers 13 are mounted on and extend forwardly from the press-bed in a manner well understood.

Spaced from its sides at points 20 and also spaced from the front of the standardizer at its top at 21, the standardizer is cut away rearwardly and downwardly, the end of this'cut stopping at a point 22 at a considerable distance from the bottom of the standardizer. The said cut-away portions of the standardizer adjacent the points 20 permit the standardizer 5 to receive the lower beveled end 26 of the chase 26. The standardizer also has a cut-away portion 23 which extend from the front 2% to the rear 25 of the standardizer, the rear portion of this cut being inclined downwardly at 23, as best shown in Fig. 4 of the drawings. The cut-away portion 23 permits the standardizer 5 to secure a chase firmly in position,

although the chase may be considerably :arped.

The cuts and inclined portions of the standardizer are provided to facilitate the clamping of the lower portion of the chase 26, the upper )ortion of the chase 26 being secured in the usual manner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A job press standardizer having a lower edge for engagement by fingers on a press-bed, means for detachably securing the sides of the standardizer to the sides of the press-bed, the standardize-r having a cutaway portion spaced from each side and extending from the front to the rear and through the top of the standardizer.

2. A job press standardizer having means by which it may be secured to a press bed, the stannardizer from its top and from points spaced from its sides being cut away downwardly and rearwardly, there being an additional central cut-away portion in the st ndardizer which is spaced from the said points the additional cut-away portion extending from the front to the rear and through the top of the standardizer.

3. A job press standardizer having means by which it may be secured to press-bed, the standardizer from its top and from points spaced "from its sides being cut away downwardly and rearwardly, there being an additional central cut-away portion in the standardizer which is spaced from the said points, and an additional cut-away portion extending from the front to the rear and through the top off the standardizer.

l. A job press standardizcr having means by which it may be secured to a press-bed, the standardizer from its top and from points spaced from its sides being cut away downwardly and rearwardly, there being an additional central cut-away portion in the standardizer which is spaced from the said points, and an additional cut-away portion extending from the front to the rear andthrough the top of the standardizer, the

standardizer being inclined downwardly at the rear of the said additional cut-away portion, the incline being at an angle to the incline of the first mentioned cut.

A job press standardizer having means by which it may be secured to a press bed, the standardizer from its top and from points spaced from its sides being cut away downwardly and rearwardly, there being an additional central cut-away portion in the standardizer which is spaced from the said points, the additional cutaway portion extending from the front to the rear and through the top of the standardizer, the standardizer being inclined downwardly at the rear of the said additional cut-away portion, the inclination being at an angle to the incline of the first mentioned cut.
